Title: Schottky barrier diode and process therefor
Inventor: ASANO TETSURO
IPC: H01L29/872
Filed: 2002-07-26
Granted: 2006-11-21
Abstract: This invention solves the problem with a conventional process having a difficulty in controlling the etching of a schottky connection of a schottky barrier diode which contains a thick layer of polyimide and a part where a mesa etching is performed and a miniaturization of the chip is hindered. This invention proposes a new schottky barrier diode of a chemical semiconductor, planar type by providing an n type and an n+ type ion implant region on the surface of the substrate to become an active region, whereby the mesa and the polyimide layer can be eliminated. As a result the cost of the wafer is reduced and size of the chip can also be reduced as the distance between electrodes can be reduced. The high frequency characteristics can be improved. The GaAs layer is not etched when the schottky electrodes are formed, and a schottky barrier diode with excellent repetitivity can be obtained.
